Pull request overview
Updates the structured-output AIAgent.RunAsync<T> wrapper to preserve the caller’s synchronization context so continuations execute on the expected thread (notably for Durable Task orchestrations).
Changes:
- Switched the await in
AIAgentStructuredOutput.RunAsync<T>fromConfigureAwait(false)toConfigureAwait(true). - Added an in-code rationale explaining why capturing the synchronization context is required for durable orchestration scenarios.

Motivation and Context
The
RunAsync<T>method in used ConfigureAwait(false), which schedules continuations on an arbitrary thread. This causes the orchestration to get stuck when the agent runs inside a durable orchestration (e.g., DurableAIAgent), whose dispatcher requires continuations to execute on the orchestration's main thread.Description
RunAsync<T>methods to DurableAIAgent (marked as new) with ConfigureAwait(true) to preserve the orchestration's synchronization context. All four overloads are provided.AgentResponse<T>.IsWrappedInObject publicly accessible.AgentResponse<T>.More details:
In this PR: #3761, several durable agent samples that are run from integration tests are failing. These samples are stuck and never finish. Running them locally shows that the issue occurs in the samples related to durable orchestration scenarios with more than one agent. The first agent in the scenarios executes successfully, but the call to the next one never returns.
